What is the Normal Packed Cell Volume (PCV) or hematocrit range for females? What is the average %?

normal range: 38% - 46%

average: 42%

What is the Normal Packed Cell Volume (PCV) or hematocrit range for males?

normal range: 40% - 54%

average: 46%

Micro Hematocrit or PCV

determines what proportion of whole blood is composed of cells and what proportion is composed of plasma

PCV

Packed Cell Volume

Why do males have higher hematocrit?

testosterone; stimulates the bone marrow to produce more red blood cells

What is the percentage of Neutrophils?

60%

What is the percentage of Lymphocytes?

30%

What is the percentage of Monocytes?

5%

What is the percentage Eosinophils?

2%

What is the percentage Basophils?

>0.5%

1-5: Identify cells and list functions

1. Lymphocytes: T, B, NK Cells; cancer cells

2. RBC: oxygen transport, CO2 removal

3. Neutrophils; phagocytes that kills and ingest bacteria and fungi

4. Eosionophils; targets parasitic bacteria

5. Basophils; releases histamine to trigger inflammation during allergic reaction or fever

6. Monocytes; MACROphages that engulf bacteria, viruses, and dead cells

Identify blood type?

From which donors could this person receive blood?

AB-

donors with AB-, A-, B-, or O- blood types

How to calculate PCV using a ruler?

PCV of a male?

Divide the first line of where the blood stops by the second line of where the plasma stops

example:

2.7/5.5 = 49%

What does it mean when the blood sample clumps or agglutinate?

Indicates presence of the antigen of the blood

Ex: Anti A Serum clumps = Precense of A antigens

Ex: Anti A Serum does not clump = No A antigens

What does it mean if the Anti-D (Rh) serum clumps or agglutinate?

Clumping = Positive (+positive+); The red blood cells have the Rh protein.

No Clumping = Negative ( −negative−): The red blood cells lack the Rh protein. 

What is the universal donor?

O negative

What is the universal recepient?

AB positive

What blood can AB+ receive?

ALL —— (A+, A-, B+, B-, O+, O-, AB+, AB-).

What blood can AB- receive?

AB-, A-, B-, O-

What blood can A+ receive?

A+, A-, O+, O-

What blood can A- receive?

A-, O-

What blood can B+ receive?

B+, B-, O+, O-

What blood can B- receive?

B-, O-

What blood can O+ receive?

O+, O-

What blood can O+ receive?

O+, O-

Neutrophils function

most abundant; 1st responder to bacterial infections; kill phagocytosis & respiratory burst

Lymphocytes functions

agranular; fighting infections, destroying cancer cells, and creating immunological memor

B Lymphocytes (B cells): Produce antibodies that neutralize pathogens like bacteria, viruses, and toxins.

T Lymphocytes (T cells): Destroy the body's own cells that have been infected by viruses or turned cancerous.

Natural Killer (NK) Cells: Act as rapid responders, identifying and killing abnormal or cancerous cells in the early stages

Monocytes functions

u shape nucleus; differentiate into MACROphages; big phagocytoic eating cells; destroy microbes and clean up dead tissue following an infection

Eosinophils Functions

orange/pink stain granuals; deal with large parasitic infections like worms; attack and destroy large infectious bodies; mediate severity of allergic reactions) reduce inflammation caused by basophils)

Basophils function

granular leuokcyte; dark purple; secrete histamine which causes inflammation associated with fever

Cause of low hematocrit

Anemia: low RBCs

Cause of high hematocrit

Polycythemia; high RBCs

Normal range percentage of Neutrophils

40%-60%

Normal range percentage of Lymphocytes

20%-40%

Normal range percentage of Monocytes

2%-8%

Normal range percentage of Eosinophils

1%-4%

Normal range percentage of Basophils

0.5% -1%
